Motion analysis is a research area focused on studying and understanding human or animal movement patterns and mechanics. This field utilizes various tools and technologies, such as motion capture systems and computer simulations, to quantify and analyze different aspects of motion, including velocity, acceleration, gait analysis, and joint movements. Motion analysis is commonly used in sports science, physical therapy, biomechanics, and robotics to improve performance, prevent injuries, and develop new technologies that mimic natural movements. Researchers in this field often collaborate with experts in engineering, physiology, and psychology to gain a comprehensive understanding of human and animal motion.
